As a new engineer for a traffic congestion mitigation company, you have been tasked with developing a Java Swing GUI that displays time, traffic signals and other information for traffic analysts.

  •  1. Current time stamps in 1 second intervals
  • 2. Real-time Traffic light display for three major intersections
  • 3. X, Y positions and speed of up to 3 cars as they traverse each of the 3 intersections

Some of the details of the simulation are up to you but the following guidelines will set the guardrails:

  • 1. The components listed above should run in separate threads.
  • 2. Loop through the simulation with button(s) providing the ability to start, pause, stop and continue the simulation.
  • 3. You will need to use basic distance formulas such as distance = Speed * time. Be sure to be consistent and define your units of measure (e.g. mile/hour, versus km/hour)
  • 4. Assume a straight distance between each traffic light of 1000 meters.
  • 5. Since you are traveling a straight line, you can assume Y = 0 for your X,Y positions.
  • 6. Provide the ability to add more cars and intersections to the simulation through the GUI.
  • 7. Don’t worry about physics. Assume cars will stop on a dime for red lights, and continue through yellow lights and green lights.
  • 8. Document all assumptions and limitations of your simulation.
